Breed neck is beautiful. I had one in a 70's Ibanez Artist which had a Maple neck, Mahogany body with carved maple top. It sounded very clear in that guitar. First time I head the Breed pickups was in an Ibanez with a basswood body. I hated those pickups in basswood. Steve at DiMarzio told me that the Breed bridge model is based on the Double Whammy DP 150 which is mid focused.
Instant VH and 80's metal tones. KILLER for those type sounds. Also, it sounds reeeeeally great in parallel.
BLECCH! Godawful. I've hated that pickup in every guitar I played that had one. I once bought a used guitar that had a Tone Zone in it. I played with the height adjustment for a week because that's supposedly the secret to make them sound amazing. Sounded like shit no matter what I did.
AMAZING. I had one in a Peavey Wolfgang and it slayed in that guitar. DiMarzio calls it a fat PAF tone, but the lows are clear and pretty tight. Beautiful mids that cut and a very nice clear top end. I play old school metal and hard rock and the AZ is a weapon. Sounds sweet when played clean, too.
I put one in my '87 Kramer and it's never coming out of that guitar. To me, the Aldrich is a perfect pickup. It can do anything and do it very well. It's the one guitar I own that I'll never sell. It has the Suhr Aldrich (bridge model) and 2 DiMarzio HS-3's. Perfect for me. I play old school metal and hard rock and the Aldrich has always made me smile.
